Clutch Rattle
 

I don't know if there is another thread to this, but here goes...

I have about 7k miles on my Z and I've been having this "problem" ever since I got my car..
Being that this is my first manual car, I don't know too much.

When I depress the clutch while switching gears, I feel the clutch rattling like crazy under my foot, like it's having a seizure or something. It doesn't jump and go all over the place, it just feels like it's going crazy. Like it's tapping back at my foot. This also happens when it's fully depressed.

Is there a problem or is it just because of the car?

It's pretty weird cuz after reading some posts about driving barefoot, I had to try it. It felt really nice. When I did this, I didn't feel anything.. lolz..

dunno, just thought I might throw this out and try to get a more technical explanation to this..

your responses are appreciated..

Thanks in advanced..

i feel that too. like when i'm in first, waiting to make a left turn with my foot on the clutch. sometimes it annoys me if i'm holding the clutch down for a bit because i'm stuck wwaiting to turn. it feels weird but i think its normal.

yea.. it does get annoying, but again, like all tranny problems with the Z, I think it's a normal thing too..

I was just reading a thread "Z vs Gen" Gen or GC = genesis coupe and there were a lot of interesting facts on there. You should read it, it's quite funny, yet very technical..

oh and btw, thanks for your input.

Mine does this too....it can't be normal....at least in my opinion at least. I've had 3 other 350z cars....and this is 370z is the first one to do this. I thought maybe it was the flywheel or pressure plate....not necessarily the clutch. I'm taking it in this afternoon to have it looked at......I don't want to because of rental car costs, etc.

This is completely normal. Everyone has said that their clutch has a little vibration to it.

i concur

Maybe when I'm at the dealer ill test drive another Z to see if it does it as well.

Mine does that too, if im at a red light and in 1st gear and im holding the clutch down waiting to go, I feel it rattling a little bit. I have driven a few 370Z's and also i owned a 40th anniversary before this and that did it too, so im almost positive its normal.

Throw-out bearing. Call it "foot massage."

Lol......so bad throw-out bearing? Or normal throw-out bearing?

Dealer wants me to bring it back when their Z specialist is in town. Service Advisor couldn't hear or feel it......yet when I got back in the car I felt it immediately.

After driving it with me, he said the car acted like it was double-clutching...weird....lol.....I said, you mean the rev-sync? He didn't know what that even was.

I can't believe this sound and feeling is considered normal. If I had a lighter flywheel, I'd expect this....is the stock 370Z flywheel light compared to a 350Z flywheel?

I don't know whether to laugh or cry about the SA's comment about double clutching!

I get this, too. It is more noticable sometimes. From what I've read here it is "normal" for these cars. Until of course you need a new clutch or throw out bearing.

I'll probably bring it to the attention of the SA when I go in for service (this will be my first service appt.) just to get it on record in case something goes wrong down the road.

Ok. first of all, if u have the rattle sound on 1st 2nd and 3rd gears u cant shift and if u hear it in 4th 5th and 6th gears u should kill yourself. Now that sad plz allow me to explain my self i recently purchased a 2010 nissan 370z i had that rattle since day 1 and since i live in new york city Bk (not Burger King ) its all stop sign every 100 yards or less i currently put over 900 miles on it, every time i take it out i practice shifting and that rattle is always the same and also gear grinding on 3rd and 5th until i drive for about an hour and it dissipates i don't hear it anymore and am like WTF? Where is it? so then i turn to the post as i read the post everyone has this problem so am thinking ( Duh) read the damn manual see what the manufacturer says and they say that if u do hear rattle ur shifting is wrong basically 1) the clutch has to be in all the way in every shift maybe not 5th to 6th but definetly 1 to 2 to 3 to 4 to 5 2) when u shift the gears u must give half a sec delay between shifts like 1 to N (pause on N for about half of a sec then) N to 2 then when rdy back to N (pause on N for about half of a sec then) N to 3 when rdy 3 to N and so on this shifting technique is done when ur moving slow basically the faster you drive the faster the shifting has to get. 3) this is the most important thing is the connection when you let go of the clutch must be smooth ( sometimes when u feel the cars tranny connect to the flywheel dont let go too early but wait about half a sec to sec for them to synchronize then let it go ) it takes practice but remember practice makes it perfect i drive now barely ever hearing the rattle. As soon as i start to f@ck up the rattle comes back cold or hot tranny tried it on both. So try this out tell me what are ur results. :tup:

PS. this tranny is very sensitive and nasty u need skill to weld it, but its strong and when you get it all right in combo OMG the engine just purrrs like a kitten very smooth very nice.

I feel the clutch rattle too.

sometimes its especially noisy for a minute or so when you've, lets say, driven home from work, and pull into your driveway/garage and you get out with the engine still running the clutch sounds like its rattling, then it goes away. anyone else have this happen?

I think it is something with the input shaft rattling according to the 350 guys. Of course it sounds like a throw out bearing to me. It is annoying.

I pulled up to my friendly Dunkin Donuts drive thru the other day and was sitting there enjoying my marbles inside my tranny (Sounds like it to me). I raised the idle a bit (100 rpm maybe) and it went away. Hmmm I thought. I'm not really a fan of these trannys but si far so good. I just try to ignore the noises................ I said "try". :shakes head:

Could it be that the engine and tranny are not braced enough and that is where the problems I read about are coming from ?

Previously when driving in garage after a drive, I noticed a sound like coolant boiling over into the overflow resevoir you get from heat picking up since you came to a stop. I usually have the radio on so I sort of ignored it. Yesterday I noticed I could feel it in the clutch pedal, then I noticed the noise went away if I let off clutch and put it in nuetral. I guess this is what the rest of you guys call the clutch rattle? I hate it when you take something to the dealer and they say they don't hear it or " Oh, that's normal" I was thinking about taking it in, now it seems this is normal

the dealer don't wanna fix yah sh iiiit man they are a bunch of pricks... I get use to the rattle because when I had my 98 ex civic I had poly urethane motor mount inserts and man that was a bi ttch rattle loud as fc uuuuuuuck but you get use to it just give it time. if your tranny Fc uuuuucks up and you modified your z and bring it to them they;ll say you done that shiiiiiiii t ahhahah

I have same problem!!! It is hella annoying!!!!!!!!! :(

I'm not big fan of nissan tranny!!!!!! ANYONE GOT THIS FIXED ON UR Z???

So I sat in another forum member's car the other day......he has the rattle as well...just not as bad as mine. He bled his clutch fluid because he suspected air was in there.

I'm not sure if this helps, but has anyone else bled their clutch to see if it made a difference?

dame.. Mine is getting worst!!!! Just can't stand it sometimes!!:(

This z is no different from any other z.. Guys with z32s,z31s these things can be a bit womanish from time to time... But like all z's once u get them down... Well that's why u can't have just one ;)

Just gotta roll with the punches and if u take care of her she'll take care of you.

I feel it as well... not to mention my throw out bearing seems to be making more noise than normal. It only has 14k miles on it so far and the sound seems to go away when I press the clutch down.

When driving the car at low speeds it also tends to make a clunking sound.

I don't think its anything serious, could just be the bearings that are used in the clutch kits, but I find it a little loud for a new car.



This may be related to the CMC issue I read about on here. Failing or weak CMCs could be wearing out the other clutch components faster than normal... I don't think that is going to affect the TOB but hey, you never know. ;-)
